builder property
Builds the child of this widget.
Passed with the InteractiveViewer.builder constructor. Otherwise, the
child parameter must be passed directly, and this is null.
{@tool dartpad} This example shows how to use builder to create a Table whose cell contents are only built when they are visible. Built and remove cells are logged in the console for illustration.
** See code in examples/api/lib/widgets/interactive_viewer/interactive_viewer.builder.0.dart ** {@end-tool}
See also:
- ListView.builder, which follows a similar pattern.
Implementation
final InteractiveViewerModifierBuilder? builder;
